COTTON-HULLER BREAKER BAR.

Application filed February To all whom t may concern:

Be it known that I, IVILLIAM L. HANCOCK, a citizen of the United States, residing at Dallas, in thc county of Dallas and State of Texas, have invented certain new and useful Improvements in Cotton-Huller Breaker Bars, of which the following is a specication.

My invention is an improved breaker bar for a cotton hulling and cleaning machine and is more particularly an improvement upon the breaker bar shown and described in my Letters Patent of the United States, No. 1,526,144, dated February 10,1925.

In the drawings:

Figure 1 is an end elevation of a part of a hulling and cleaning machine such as is shown in Figure 1 of my Patent No. 1,526,144, showing my improvements and their relation to the old parts, the inner parts being in dotted lines;

Figure 2 is a front View of my improved breaker bar, on a larger scale, looking in the direction of the double arrow, Figure 1;

Figure 3 is a view of an end of the breaker bar of Figure 2, in plan, both ends being identical in construction;

Figure 4 is a section on line 4-4 of Figure 2 and Figure 5 is a detail of a tooth.

The cotton is fed to the huller cleaner through chute 8 and reaches the feed rolls 9, turning as indicated by the arrows, by which it is fed in a somewhat compressed bat to the breaker roll 10 rapidly turning in the direction indicated by the arrow, the teeth 102L4 ofthe roll 10 strike the bat hammer like blows, breaking the bolls, without grinding them. All this is shown and described in my Patent No. 1,526,144, and is repeated here to make clear the relations of the novel parts to be described. I have marked the parts of the old machine hereinabove mentioned in accordance with their indicating` numbers in Patent N o. 1,526,144.

To one side and in front of the breaker roll 10 is set a cooperating shaft 111 supported in bearings 112, in the frame 118 of the machine. This shaft 111 carries at either end brackets 114, secured to the shaft by set screws 115 or otherwise, and carrying seats 116 on its depending ends for a transverse angle plate 117 which is fast upon the seats of the two end brackets and connects the depending ends of the brackets.

24, 1925. Serial NO. 11,094.

Between the hubs of the brackets 114 and filling the space I mount upon the shaft 111 a multiplicity of teeth, 118, the hubs 118 of which are free to turn upon the,

shaft. Rearwardly extending from each hub 118a is a tail-piece 118b projecting across the upper edge of the cross member 117. At the free end of each tail-piece 118" is attached a tension spring 119 the lower end of which is attached to the lower part of the cross-member 117 (see Figure 4). It is obvious, of course, that in place of the tension spring a spring of another form or type might be employed or the weight of the tailepiece might be relied on to normally hold the tooth in position. These are obvious equivalents.

At one end of shaft 111 is secured by set screws or the like the hub 12()a of a lever 120 (see Figures 1 and 2) the hub serving also as a collar to restrain longitudinal movement of the shaft 111, in cooperation with collar 111a at the other end of the shaft. This lever 120 is connected by a' link member 121 with a position securing device 122, preferably a toothed sector and latch as shown in Figure 1. vious that the shaft 111 with its brackets 114 and cross member 117 may be swung and secured in a desired position and in this way the teeth 118 may be set forward or back toward the roll 10 and across the path of the material, the teeth 118 passing in their advanced position, between the rows of teeth 10a, on the roll 10. Beneath the teeth 118, across the machine, is set a comb with upstanding teeth 18, the teeth 18 being opposite the rows of the teeth 10a on the roll 10 and between the teeth 118. When the teeth 118 are retracted by turning the shaft 111 they are received in the spaces between the teeth 18 and a continuous sur face is then presented upon that side of the cotton passage.

It will now be clear that the teeth 118 may be adjusted, advanced or retracted, by turning the shaft 111 and locking it in position by means of the latch and toothed-sector mechanism, 122. Also that in case any hard material, such as for example, a stone, passes the feed rolls 9, and is carried down upon the teeth 118, only the tooth or teeth directly in its path will be affected and that this tooth or teeth can yield downward under the impact against the force of a spring It will now be ob-V 119 and as soon as the stone or other object has passed, the tooth affected will return to its adjusted position, the shaft lll and the other teeth upon it, being unaffected and Continuingl to perform their designed function Without interruption.

I Claim:

l. In a boll-breaker and cotton cleaner, a chute; a boll breaker roller beneath the chute; a shaft in front and to one side of the roller; brackets fast at either end of the shaft; a cross-member connecting the brackets; teeth loosely mounted upon the shaft with capacity t0 turn thereon, the rear end of the teeth normally resting upon the cross-'member.

2. In a boll-breaker and cotton cleaner, a chute; a boll breaker roller beneath the Chute; a shaft to one side and in front 0f the roller; brackets fast at either end of the shaft; a cross-member connecting the brackets; teeth loosely mounted upon the shaft with capacity to turn thereon the rear end of the teeth extending over the cross-member; means to keep each tooth normally pressed against the crossemember With liberty to turn away from it; means to turn the shaft and teeth and secure them in a designed position.

Signed at Dallas, Texas, this 16th day of February, 1925.

WILLIAM L. HANCOCK.
